Fluensulfone is an agricultural and horticultural nematicide. It has a moderate oral toxicity and low by dermal and inhalation routes. It is an irritant and skin sensitiser. It can be expected to dissipate rather rapidly in the environment and has a low to moderate toxicity to fauna and flora.
Hazard alerts
The following Pesticide Hazard Tricolour (PHT) alerts are based on the data in the tables below. An absence of an alert does not imply the substance has no implications for human health, biodiversity or the environment but just that we do not have the data to form a judgement. The alerts for Highly Hazardous Pesticides (HHPs) are based on applying the FAO/WHO (Type 1) and the PAN (Type II) criteria to PPDB data. Further details on the HHP indicators are given in the tables below. Neither the PHT nor the HHP hazard alerts take account of usage patterns or exposure, thus they do not represent risk.
Systemic with rapid contact action, affects all active stages of the nematode life cycle by inhibiting the feeding and motility of adults and juveniles and

Commercial production
Commercial production of fluensulfone follows a sequence built around constructing a heterocyclic thioether, converting it to the corresponding sulfoxide or sulfone, and introducing the fluoroalkenyl side chain. The key industrial step is the dehalogenation of a di halogenated fluoroalkyl intermediate to generate the characteristic CF=CF2 moiety. Upstream, manufacturers prepare a thiazole based thioether precursor, then oxidise it under controlled conditions using an oxidant and a metal oxide catalyst to obtain the sulfone.
